2 Claims.

The invention relates to sole pressing members for shoe presses, andparticularly to a pressing member employed in a shoe press for cementingsoles on shoes. These shoe presses comprise a base which mounts a frameby which the sole pressing member is carried. The shoe, to which thesole has been applied by cement, is disposed on the sole pressingmember, and a sole last is inserted in the shoe to bear against the solethereof. Pressure is then applied to the last by suitable means, wherebythe last and shoe sole are pressed against the sole pressing memberwhile the cement applied to the sole is setting. In order for the deviceto achieve the best results, it will be obvious that the sole pressingmember should be shaped to conform to the contour of the shank and soleof the shoe to provide the proper support for the shoe while the sole isbeing cemented.

This support should obviously be a face contacting support for theentire surface of the shank and sole of the shoe.

It will be seen that, to be practical, some provision must be made inthe sole pressing member to accommodate the various contours of thesoles and shanks of shoes of different sizes and makes and havingdifferent heel heights, since otherwise an almost infinite number ofsole pressing members would be required for use in connection with 7each shoe press. To provide an adjustable sole pressing member operableto accommodate any shoe is therefore the principal object of thisinvention.

A further object is to provide a device of this character whichautomatically shifts to accommodate its shape to the contour of the soleand shank of a shoe pressed thereagainst.

#A further object is to provide a device of this character comprising aframe and a pair of cooperating plates shiftably carried by the frame.

A further object is to provide a device of this character comprising aflexible pad which is supported by a pair of shiftable cooperatingplates.

With the above and other objects in view, the invention resides in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawing, described and claimed, it being understood that changes inthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from the spirit of the invention.

Referring to the drawing, which illustrates the preferred embodiment ofthe invention, the numeral I0 designates the shoe press which comprisesa base I l on which is mounted my improved sole pressing member [2. Thesole pressing member I2 is preferably provided with laterally projectingears l3 which are apertured to receive the lower ends of vertical rods14 which support the ends of a horizontal bridge member l5, spaced abovesupport or sole pressing member 12. A pair 25 of spaced bosses l6 areprovided in bridge member I5, which bosses are provided with threadedvertical apertures in which bolts ll each provided with an operatinghandwheel 18 are mounted. The bolts I! are each positioned to bear upona sole last I9 which is fitted in a shoe 2B which is mounted upon thesole pressing member l2.

The sole last l9 may be of any desired construction, but I prefer toemploy a last of the construction illustrated in my Patent No.1,928,258, issued September 26, 1933. This construction of last, asillustrated in Figure 6 herein, comprises a base plate 2! which ishinged at its rear end at 22 to a shank plate 23. A handle member 24projects upwardly from plate 2 l, and the bolt ll bears on the upperface thereof to apply pressure to the last. A recess 25 is formed in oneside face of handle 24, which recess is of the shape of a sector of adisc. A flange 26 of sector shape fits into recess 25 and is carried byplate 23. A plurality of apertures 21 are formed in the flange 26 andare selectively brought into registration with an aperture formed inhandle 24, through which registering apertures a pin 28 may extend tohold the shank plate 23 in desired angular relation to base or soleplate 2| to conform to the inner contour of the sole and shank of ashoe.

The sole pressing member l2 against which the last I!) presses a shoesole while the cement applied thereto is setting is comprised of a frame39, preferably cast and shaped to receive both right and left shoes.Each section of the frame 30 is defined by a vertical curved'plate 3 I,the rear ends of which are connected by a vertical plate 32 of lesserheight than plate 3|. A transverse plate 33 is disposed centrally ofeach section of the frame at the lower side thereof for purposes to behereinafter set forth. An inwardly downwardly inclined flange 34projects from the front of each section at a height substantially equalto the height of plate 32, and is provided with a longitudinallyelongated slot 35 extending therethrough. A pair of recesses 36 areformed in opposed relation in the plate 3| in rearwardly spaced relationto bar 33, and extend from the upper edge of plate 3! to a pointsubstantially horizontally aligned with the upper edge of plate 32.

A sole plate 31 of a shape conforming to the forward portion of eachsection of frame 30 and of a size to move freely therein is disposed ineach section of frame 39, the upper face of said plate 3'? preferablybeing slightly concaved in accordance with the normal convexity of thesole of a shoe. A perpendicular pin 38 depends from the bottom of plate3'? adjacent the forward end thereof to fit into the slot 35 of flange34. The plate 31 terminates in rearwardly spaced relation to bar 33 andis provided with a depending transversely extending convex bead 39 atits rear end. A shank plate 49 is disposed in the rear portion of eachsection of the frame 30 and conforms With the shape of said frame and isshiftable relative to the frame. A pair of opposed laterally extendingpins 4| project from the sides of plate es and are mounted in recesses36 to pivotally support said plate in said frame. The plate 40 is of alength to engage plate 32 at its rear end when substantiallyhorizontally positioned and to underlie the rear end of plate 31 at itsforward end. The forward end of plate 40 is provided with a transverselyextending concave lip 42 which normally receives the convex bead 39 ofplate 37, said lip being downwardly off-set from plate 40, whereby, whensaid plates 3'! and 40 are disposed in parallel relation as illustratedin Figure 4, the upper faces thereof will be substantially aligned.

A flexible pad 43 conforming to the shape of each section of frame 30 ismounted in each of the frame sections and is supported by plates 31 and43, said pad preferably being formed of soft rubber. r

In the use of the device, the shoe is disposed upon pad 43, whereby saidpad supports the sole and shank thereof. The last 19 inserted in theshoe and adjusted to conform in shape to the inner contour of the soleand shank of the shoe is then pressed downwardly by bolt I! to deformpad 43 and shift plates 31 and 40 to relatively angular position,as'illustrated in Figure 3. The pressure 7 applied to pad 43 and plates31 and 40 shifts said plates and flexes said pad whereby the pad assumesand is firmly supported by the plates in a position wherein it conformsto the contour of the lower face of the shank and sole of the shoe.While the pressure is so maintained the sole and shank of the shoe arefirmly pressed at the upper and lower faces thereof and throughout thefull extent thereof to permit the cement applied to V the sole, as inapplying a half sole to the shoe, to firmly set and adhesivelysecuresaid half sole to the shoe. It will be observed that thisconstruction of sole pressing member is operative to adjust its positionto accommodate the contour of the shank and sole of any shoe.

The invention having been set forth, what is claimed as new and usefulis:

j 1. In a sole pressing member for a shoe press, a frame including avertical plate configured to receive the front portion of a shoe and aflange projecting inwardly of said frame at the front thereof, .saidplate being provided with a pair of opposite recesses adjacent the rearthereof, a pair of cooperating plates mounted in said frame, one of saidplates being supported by said flange, ears projecting intermediate thelength of the other plate and disposed in said recesses to pivot saidplate, said last named plate engaging said first plate, and a flexiblepad mounted on said plates, said pad flexing to conform to the contourof the sole and shank of a shoe pressed thereagainst and shifting'saidplates to relatively angular position to accommodate said flexing.

2. In a sole pressing member for a shoe press, a frame, a pair of platesshiftably carried by said frame, a convex bead carried by the bottomface of one plate at one end thereof, and an offset 45 concave lipcarried by the other plate and underlying said bead, and a flexible padmounted on said plates, said pad flexing to conform to the contour ofthe shank and sole of a shoe pressed thereagainst and shifting saidplates to relatively angular position to accommodate said flexing.
